This article mainly explains "SpringBoot+nginx how to achieve resource upload function", the content of the article is simple and clear, easy to learn and understand, the following please follow the editor's ideas slowly in depth, together to study and learn "SpringBoot+nginx how to achieve resource upload function" bar!

1.nginx installation and configuration

The server used by the editor is Aliyun's lightweight application server, and the system uses ubuntu. Remember to open the 9090tcp port, or if you don't use port 9090 as the server port.

Installation

First of all, it is necessary to get the installation package. A nginx-1.11.3-ubuntu.tar.gz https://pan.baidu.com/s/1vvb41qkoj4vqfyfckxbkja (password 45wz) is provided here.

The editor puts the installation package in / usr/nginx, goes to the directory, and then executes tar-zxvf nginx-1.11.3.tar.gz to extract it.

Configuration

Modify / usr/nginx/conf/nginx.conf:

Server {listen 9090; server_name localhost; location ~. (jpg | png | jpeg | gif | bmp) ${# recognizable file suffix root / usr/nginx/image/; # the mapping path of the picture autoindex on; # enables automatic indexing of expires 1h; # expiration time} location ~. (css | js) ${root / usr/nginx/static/; autoindex on; expires 1h;} location ~. (avi | mov | rmvb | rm | flv | mp4 | 3gp) ${root / usr/nginx/video/; autoindex on; expires 1h;}

The modification of the modification, the addition of the increase, do not delete it indiscriminately

The last step is to start nginx and execute. / usr/nginx/sbin/nginx

Here, the server nginx is ready.

You can try downloading the picture 01.jpg in / usr/nginx/image, and then see if the picture can be accessed locally.

2. Springboot to upload resources

Pom.xml:

Org.springframework.boot spring-boot-starter-parent 2.1.7.release org.springframework.boot spring-boot-starter-web 2.1.7.release org.springframework.boot spring-boot-starter-test 2.1.7.release test org.apache.commons commons-lang3 3.8.1 org.apache.commons commons-io 1.3.2 commons-net commons-net 3.6 commons-fileupload commons-fileupload 1.3.3 org.projectlombok lombok 1.16 . 22 com.jcraft jsch 0.1.54 joda-time joda-time 2.10.3

Appilcation.yml:

Ftp: host: own server ip username: server account password: server password port: 22 rootpath: / usr/nginx/image img: url: http://ip:9090/ # ftp.img.url may not be added. This is just to return the file path after the file is uploaded successfully.

Tool class idutils.class (modify upload image name):

Import java.util.random;public class idutils {/ * generate random picture name * / public static string genimagename () {/ / take the long shaping value of the current time including millisecond long millis = system.currenttimemillis (); / / plus three-digit random number random random = new random (); int end3 = random.nextint (999); / / if less than three digits before 0 string str = millis + string.format ("d", end3); return str;}}

Launch the project, a wave of postman artifacts

Note:

1. If you want the video to be uploaded with the picture, just modify the nginx.conf configuration file and add the corresponding video suffix. The code has not changed, and it is also placed under / usr/image after upload, otherwise the file can be uploaded, but cannot be accessed.

two。 The above code uploads API is used to upload multiple files.
